echo 'Error: Attribute `nixosConfigurations.base.config.system.build.createScript` >&2
echo '       not found in flake

I don't see that attribute set in the example config

https://github.com/Lassulus/flakes-testing/blob/master/flake.nix

What am I missing?

--mode destroy --yes-wipe-all-disks ignores --yes-wipe-all-disks and gets stuck waiting for input

and

--mode destroy,format,mount --yes-wipe-all-disks also gets stuck ... maybe a missing sync?

lassulus: I have added the debug output for the "disko" mode

1. Change all UUID partition references to /dev/sda or /dev/sda2.

2. Made sure that btrfs was present during boot.

3. Expanded the boot device definition to have more details vs. the previous version which just had the path.
